   * RSO: [[https://arxiv.org/pdf/2309.06657|Liu et al 2023 - Statistical Rejection Sampling Improves Preference Optimization]] Uses rejection sampling with CE loss.  Sample outputs, and accept or reject them based on the reward.  Then fine-tune on the accepted ones use CE loss.  Very principled, easy to implement.  Says they get a benefit over DPO by using a reward model.

For instance, Bai et al. (2022); Touvron et al. (2023) typically iterate the RLHF process on a weekly cadence, where the fresh RLHF models are deployed to interact with crowdworkers and to collect new human preference data."
